During nucleate pool boiling of pure water and water with cationic surfactants, the motion of bubbles and the temperature of the heated surface were recorded by both a high-speed video camera and an infrared radiometer. All experiments were performed at saturated boiling conditions. The boiling curves for various solutions were obtained and compared. The results show that the bubble behavior and the heat transfer mechanism for the surfactant are quite different from those of clear water. In this study the examples of the irregular behavior of nucleation sites and their interactions are presented.
